Abstract

Series comparative measurements of the thermal conductivityK of single‐crystal silicon have been extended to 1000°K. The results show that K remains nearly linear in T−1 to 1000°K and has a value of 0.29±0.06 W/cm C° at this temperature. This temperature dependence indicates the conduction is predominantly by the lattice vibrations and is limited by phonon‐phonon scattering.
